I have two Jackson chams, both females. They were previously (before I got them) in, I would say a particularly small cage. Now that I have them, I have put them in a 3 foot tall, by 2 foot wide cage EACH. (one cage for each cham) they are only about a year old, and are about 5 inches long. Do I have too big of cages for them? Too small of cages? Opinions are helpful.. please!
